Boeing's website has the YTD order tally at 197. Also, I believe Boeing has been in talks with several unannounced airlines about the 7E7, so they may still get some more large orders confirmed before year end for that type.

Under announced deals waiting for confirmation, you can include Vietnam Airlines for 4 7E7-8. Not acknowledged by Boeing yet, but the airline has announced it's intent. Also Hainan Airlines for 3 737-800s, and as already mentioned, 2 717's for Turkmenistan.

"Primaris 20 7E7-8 and 20 737-800 (will not be confirmed this year"

Yes, it should.

"some say not at all)"

It should be signed, however there is many who question whether all the aircraft will be delivered. Similar to the EK massive widebody orders for both Boeing and Airbus, as well as Air Berlin's recent mega-order.

"Widely expected to be announced before year end:"

I would also speculate on:

Qatar Airways - 20 7E7 or A350
Air Europa 2-4 A330-200 order (though seriously doubt the rumors about A350 commitment. From what I've heard, these A330's will be interim aircraft, possibly leased or second-hand. Boeing is really courting them to be another 7E7 launch customer).
China - large Boeing order. Expect @ 50-60 7E7, @ 20+ 737NGs, possibly some 777s, though less likely

"Air Asia 40+, rumoured to have gone Airbus."

Possible, but with Boeing's humiliating loss of the Air Berlin order, I have a feeling they will do everything it takes to win the AirAsia bid.

"Five aircraft in that 197 tally are U.S. Navy bound and therefore excluded."

Why? Both Airbus and Boeing count military sales as part of their orderbooks. And are these frames just going to magically appear? Of course not, they will be built on the same assembly line as all current 737NGs, and thus contribute to production output.

"I don’t have the data to post net totals but I’d be most appreciative if someone could."

At the end of Sept. (sorry, I don't have Oct. yet), cancellations stood thus:

At the moment, it's not that clear, actually. At different points in time, I've heard both. The latest I heard, however, was that Thai was going with -200ERs, though using them on regional routes. The reasoning behind this is more flexibility, and higher resale values. We'll see what happens.

Qatar apparently could sign for up to 60 7E7(orders+options),but want the 7E9 fully defined by Boeing before they will commit. They only require 8-10 7E8,so the bulk of their order will be for the 7E9.
